Show HN: Golf Swing Camera App
A developer created a free, open-source golf swing camera web app that records slow-motion video without needing to upload footage to the cloud. The app runs entirely in the browser, offering instant playback and analysis for golfers looking to improve their swing.
Background
- Golf Swing Camera is a mobile web app that uses Motion Photo (a feature capturing a short video burst around the moment you press the shutter) to help golfers record and analyze their swing without needing a dedicated high-speed camera or a second person to film.
- Motion Photos, popularized by Google Pixel phones and now available on many Android devices, capture a few seconds of video before and after the photo is taken — the app extracts the video frames to let users review their swing in slow motion.
- The author, Tim Leland, is an independent developer known for creating simple, niche tools (like a link-in-bio service and a URL shortener); this app is one of his side projects, posted on Hacker News ("Show HN") for community feedback.
- Why it matters: Analyzing a golf swing typically requires either an expensive high-speed camera or asking someone to film you. This app removes both barriers by leveraging a feature many people already have on their phone, making swing analysis more accessible to amateur golfers.
